This creates a kind of ultrasonic fragrance water oxygen machine structural improvement,Mainly by pedestal,Water storage container and shell composition,Wherein pedestal be provided with water level detecting mould group,Voltage and current detects mould group and mist device,One is wherein defined between the water storage space and the pedestal detects the enclosure space of mould group for water level detecting mould group and the voltage and current is arranged,Therefore water level detecting mould group and voltage and current detecting mould group carry out anhydrous sensing in the case where that need not touch water,If therefore need not maintain will not also occur not removing the facts for leading to accidentally actuation because of scale,Voltage and current detecting mould group of arranging in pairs or groups simultaneously can judge water position status through voltage sensing mode when water level detects mould group failure,To reach the purpose of duplicate protection.本創作一種超音波芳香水氧機結構改良，主要由基座、蓄水容器及殼體組成，其中基座設置有水位偵測模組、電壓電流偵測模組及造霧器，其中該蓄水空間及該基座之間界定一供設置該水位偵測模組及該電壓電流偵測模組之封閉空間，因此水位偵測模組及該電壓電流偵測模組在無須接觸到水的情況下進行無水感測，因此無須保養亦不會發生因水垢若未清除導致誤作動之情事，同時搭配電壓電流偵測模組能在水位偵測模組故障時透過電壓感測方式判斷水位狀態，以達到雙重保護之目的。
